People with dry eyes are advised to desist wearing contact lenses because this would further the deterioration of their eyes. It’s a wrong impression because dryness also occurs for the normal contact lens wearer. Advance technology has been a great help for people with dry eyes, because now they can wear contact lenses. With the new types of lenses available and lens care products, they can also wear them for long periods of time.
Contact lens for dry eyes stays away from eye tissue damage and corneal scars. Tears nourishes the eyes, failure to produce them leads to instability on the tear firm. Leading manufacturers and brands continue to research to face the challenges posed by dry eyes. They employ different materials like polymers and gels that has long water retentions.
Contact lenses for dry eyes are composed of special compounds with a function of checking dryness and other purposes. Silicone hydrogel not only controls water buildup but it gives a soothing effect to the eye. Despite having lesser water, it provides moisture.
Silicone hydrogel lenses are composed of materials that yield high oxygen permeability, allowing more oxygen to flow to the cornea.
There are also new polymers that are developed to address the dryness problem. Manufacturers that invest on polymers have developed Omarifilcon A for contact lens purposes. These contact lenses are purposely designed to fit the nature of the eyes and to adjust to it comfortably.To keep the lens moist and comfortable, soft contact lenses are mad of hydrophilic polymers. They will ensure that your eyes are properly hydrated.
It is also important to note that rigid gas permeable lenses are good contact lenses for dry eyes. Since this type of contact lens is made up of plastic, it is rigid hence it does not dehydrate the eye. The plastic that makes up gas permeable lenses is oxygen permeable.
Finally, it is better to check with an eye practitioner if you are suffering from dry eyes. To avoid eye complications, you must make sure that you follow all the instructions given by the eye care practitioner.
